U.S. Pat. No. 3,917,026, Aerial platform utility enclosure assembly, filed Jan. 16, 1975, allegedly describes a modular three-part preformed lightweight synthetic resin panel assembly comprising an aerial platform utility enclosure designed to be installed upon the outer structural surfaces of the frame members of an otherwise unenclosed aerial platform cage, wherein each respective panel member of the utility enclosure has an outwardly extending integrally molded tool and equipment storage compartment, with one such compartment being further provided with interiorly affixed laterally positioned rib panels to support transparent plastic accessory and parts drawers, wherein also the utility enclosure design is such that, when installed, there is no reduction in the available preexisting aerial platform operator/worker occupancy space.

U.S. Pat. No. 5,611,410, Aerial platform enclosure apparatus, filed Jul. 11, 1995, allegedly describes an aerial platform utility enclosure designed to be easily installed upon an unenclosed aerial platform bucket. The enclosure protects the worker from environmental elements without reducing visibility out of the bucket because a polycarbonate plastic such as LEXAN is used to cover the entire enclosure. Upper and lower structural components of the enclosure are constructed out of a non-conductive material. The lower structural component is firmly attached to the bucket while rotation of the upper structure and the protective cover in a full circle allows the worker to have greater access to his surroundings without having to reposition the bucket.

U.S. Pat. No. 6,470,999, Ergonomic insert for aerial bucket, filed Oct. 2, 2000, allegedly describes an ergonomic insert that reduces the risk of low-back injury to workers in aerial buckets. A combination of an ergonomic insert, an aerial bucket and means for stabilizing said ergonomic insert within the aerial bucket is also disclosed. Finally, a method for using such an ergonomic insert is also disclosed. The ergonomic insert comprises a nominally non-deformable material having foot-receiving surfaces and capable of bearing a worker's weight. Various means for supporting the ergonomic insert in a vertical position are disclosed. The method for using the ergonomic insert comprises placing the ergonomic insert into the aerial bucket from above. The ergonomic insert is positioned between the worker and the work to be performed. The worker then places a foot on one of the foot receiving surfaces prior to or while performing the work.

U.S. Pat. No. 4,883,145, Ergonomic aerial basket, filed Jan. 25, 1989, allegedly describes a simple apparatus that reduces the risk of low-back injury to workers in elevated, partially enclosed, aerial baskets. The preferred embodiment basically comprises a circular well within the floor of the basket that is surrounded by a raised footrest platform adapted to receive on foot of the worker. Between the footrest platform and a base of the well is a cylindrical wall that prohibits forward movement under the footrest platform. In operations, when the worker has to perform manual handling tasks outboard of the basket, one foot is raised out of the well and extended forward onto the footrest platform, while the other foot remains below and behind the raised foot, on the base of the well. The worker has thereby adopted a forward leaning posture instead of a forward bending posture. Consequently, the worker retains the optimal curvature of the spine, while achieving a biomechanical advantage that reduces the work demand on the lower back.

U.S. Pat. No. 4,763,758, Scuff pad with step, filed Dec. 22, 1986, allegedly describes a scuff pad with step which resides interiorly of an aerial lift bucket, or bucket liner if provided, at the bottom thereof and which includes a base portion and an upwardly extending portion extending upwardly of the base portion of a predetermined distance, the base portion has a top surface for being engaged by the shoes of said person upon standing in said bucket or liner to prevent scuffing, and the upwardly extending portion has a top surface providing a step which facilitates climbing out of said bucket or liner by the workman.

U.S. Pat. No. 6,491,272, Step assembly with a removable step for hollow poles and the like, filed Aug. 9, 2001, allegedly describes a pole step assembly with a removable step for hollow poles and the like. The step assembly includes a mounting subassembly with a mounting stud and a mounting plate with inter-engaging flat surfaces that limit relative rotational movement of the mounting stud and mounting plate about the axis of the subassembly. A clamp is provided to limit radial movement of the subassembly relative to the pole. The mounting stud of the subassembly optionally also may include a handle portion that captivates the components of the subassembly and facilitates ease of installation of the subassembly. The handle also may break away and be removed after installation of the subassembly. The step is mounted to the subassembly and may include flat surfaces that inter-engage with further flat surfaces on the mounting plate to limit rotation of the step about its longitudinal axis.

U.S. Pat. No. 3,561,563, Portable post step, filed Aug. 14, 1969, allegedly describes an integral rigid catwalk metal sheet bent along a transverse fold line to provide a post engaging portion and a step portion, the post engaging portion having a laterally inwardly extending notch for engaging the post. The post is engaged by opposing edges of the notch wherein one of the edges is the inner edge portion of the step portion. The step is placed on the post from the side and the weight of the step portion causes the unit to pivot downwardly bringing the opposing edges of the notch into engagement with the post thereby locking it in place. The post engaging portion forms an obtuse angle with the step portion and the step portion is normally positioned in a horizontal plane. A series of vertically spaced apart steps may be placed on a post and extend alternately from the post at angles of 90* to each other. Oppositely facing concave portions may be formed in the opposing edge portions for matingly engaging the rounded peripheral edge of a round post.

U.S. Pat. No. 4,763,755, Bucket release assembly for aerial device, filed Jun. 3, 1987, allegedly describes a release assembly for an aerial device for pivotally releasing a worker's bucket from an upright orientation to a horizontal orientation.

DETAILED DESCRIPTION

Clear Platform

Typical prior art platforms are opaque and an operator cannot see through them. If the platform is being used in a tight space or the operator needs to see what is just outside the platform, the clear platform increases the operator's visibility of his surroundings. When a platform is opaque there is an increased probability of the operator striking an object with the platform because of reduced visibility.

Referring now to the drawings in general, the illustrations are for the purpose of describing a preferred embodiment of the invention and are not intended to limit the invention thereto.

The invention is directed to elevating platforms with walls, panels, knee spaces, floors, doors and combinations thereof made of clear or transparent and/or translucent materials to provide high visibility to the operator. The platform is constructed using optically clear or translucent materials, either in strategic locations or having an entirely clear platform, thereby giving the operator enhanced visibility around the platform, resulting in better performance. The present invention also increases operator safety and extends the life of platforms by making it easier for the operator to avoid running the platform into objects.

The present invention provides for different combinations of materials to achieve the enhanced visibility. Some example configurations are as follows: Using a standard, opaque fiberglass platform, generally described as 100 in FIG. 1, sections of one or more walls are cut out and a clear, transparent panel 110 or panels are attached. The clear replacement section is a planar shape or an outwardly bulbous shape 120 which provides space for the knees of a squatting operator. In another configuration, the platform door is constructed of clear material. In yet another configuration, the platform is constructed in the typical fashion, but a resin system with a reflectance and refractive index similar to glass is used, yielding an entirely clear platform with similar image displacement as glass (FIG. 2).

The clear materials are attached to a typical fiberglass platform by adhesive bonding, mechanical fastening, and combinations thereof. If the fiberglass platform is made to be clear, a resin is chosen to match the reflectance and refractive index of the glass, resulting in a composite laminate that is optically clear and with similar image displacement as glass. The clear material has a refractive index of between about 1.3 and 1.7, a reflectance between about 70 and 100, negligible scattering and negligible absorbance.

For translucent designs, the translucent material is preferably between about 30% and about 70% light transmission. More preferably, the % light transmission is about 40-60%. In another embodiment, the % light transmission is about 50%. An example preferred embodiment is white polycarbonate with a % light transmission of between about 30% and about 70%. The make and model of an example preferred white translucent polycarbonate is Sabic Lexan XL102UV.

Alternatively, a fiber reinforced thermoset resin with a clear gel coat may be used to produce an entirely translucent platform structure. Translucent components such as panels, knee spaces, and doors could then be attached to the translucent platform structure. These translucent components may be made from Polycarbonate, Acrylic, Nylon, Polypropylene, fiber reinforced thermosets, and unreinforced thermosets.

Alternatively, polycarbonate, acrylic, nylon, polypropylene, fiber-reinforced thermosets, and unreinforced thermosets may be used to produce an entirely translucent platform.

In another alternative embodiment, a platform structure is made with fiberglass, an optically clear thermoset resin, and a translucent gel coat to allow light transmission but maintain privacy.

Alternatively, a reinforced thermoplastic such as Vectorply EPP-W 1500 or Vectorply EPP-W 2200 may be used to create an entire platform or platform components such as a panel, knee space, or door. The Vectorply products are a fiberglass reinforced polypropylene and they become translucent after they are processed during manufacturing of platforms and platform components.

In a preferred embodiment, the resins are acrylic-modified resins such as POLYLITE 32030-00 and 32030-10, manufactured by REICHHOLD, Research Triangle Park, N.C., USA. In one embodiment, the acrylic-modified resins include polyester resins. Preferably, the acrylic-modified resins are low-viscosity resins, low-reactivity resins, and UV-stabilized resins. Any clear or translucent thermoplastic or thermoset, impact-resistant polymer, such as polycarbonate, can be used without departing from the scope of the invention.

The invention is thus directed to an elevating platform with at least one wall; and further including at least one panel, at least one knee space, and/or at least one door. The at least one wall, the at least one panel, the at least one knee space, and/or the at least one door is formed of a clear or translucent material, thereby providing an elevating platform which provides for greater visibility to an operator. In another embodiment, the elevating platform includes at least one clear or translucent section in the at least one wall, wherein the remainder of the at least one wall is constructed out of a different material than the at least one clear or translucent section. The at least one clear or translucent section is attached to the elevating platform by adhesive bonding and/or mechanical fastening. The at least one clear or translucent section is a planar shape or a knee space formed by an outwardly bulbous shape using clear or translucent material. The knee space provides space for at least one knee of a squatting operator. In another embodiment, the entire elevating platform is constructed using fiberglass and a clear or translucent resin system such that the elevating platform is entirely clear or translucent. The clear resin system has a refractive index between about 1.3 and about 1.7. The translucent resin system has a % light transmission of between about 30% and about 70%. The clear or translucent material is fiber-reinforced thermosets, unreinforced thermosets, fiber-reinforced thermoplastics, and/or unreinforced thermoplastics. The translucent resin system is preferably white polycarbonate.

Platform Step

The present invention is further directed to a step for use in elevating platforms. Steps are located on the sidewall of a platform, and the operator uses them as an aid to get into and out of the platform. Typical prior art steps have a flange all around the step that is bonded to the outside of the platform wall (FIG. 3A). When a load is applied to the step (e.g. an operator stands on it), the bondline on the upper portion of the step flange is in tension (step is trying to pull away from the platform wall). The bondline on the lower portion of the step flange is in compression (trying to push into the platform wall). Failures typically initiate on the portion of the bondline that is in tension, and not on the portion of the bondline in compression.

In an alternative prior art embodiment (FIG. 3B), a cutout is made in the platform wall, and a step is inserted through it from the inside. The flange of the step is bonded to the inside of the platform wall. In this embodiment, the top bondline is in compression and the bottom bondline is in tension (the step is being pushed into the platform).

Both of these embodiments rely on the strength of the adhesive, rather than on the structural strength of the components.

The present invention eliminates the weakness of the prior art by having both the top and bottom bondlines in compression. As shown in FIG. 4, the present invention provides for a specifically designed platform cutout 220 in the sidewall 215 of the platform that the step fits into. The system, generally shown as 200 in FIG. 4, includes a step 210 that is specifically designed and configured to lock into the cutout 220 (FIG. 5). The step includes at least one transition 230 (FIG. 6) and at least one notch 240 (FIG. 7). The notch and opposite margin are designed such that when the step is inserted into the cutout with the bottom of the notch touching the sidewall, the opposite top flange 250 (FIG. 8) clears the cutout and is moved into the platform by pivoting the step around the notch. The step transition 230 is designed and configured such that the top and bottom flanges fully contact the inner and outer sidewall, respectively. This contact serves to provide more surface contact area between the step and the sidewall. This design provides that the upper portion of the flange compresses against the inside of the platform wall and the lower portion of the flange compresses against the outside of the platform wall, thus causing both portions to be under compression, rather than tension. Thus, all loads on the step are compressive loads.

Preferably, a second notch 260 is provided on the margin opposite the first notch, such that when the step is centered, a portion of the second side margin extends over the sidewall, covering it. This coverage provides for a seal of the cutout. Some platform assemblies that include a platform step are used with insulating liners and other platform assemblies that include a platform step are not used with insulating liners. According to ANSI A92.2-2015 Section 4.9.5.1, platforms for use with insulating liners shall not have drain holes or access openings. Therefore the platform step cutout must be sealed if the platform is going to be used with an insulating liner. The platform step is fixed to platforms the same way if the platform is or is not going to be used with an insulating liner, therefore the step cutout must always be sealed.

To mount the step in the cutout (FIGS. 9A-E), the step is first moved into place (FIG. 9A). A step notch is inserted into the cutout notch (FIG. 9B). The step is then rotated to completely insert the top flange into the cutout (FIG. 9C). The step is centered in the cutout opening (FIG. 9D). The step is then lowered until it locks into place (FIG. 9E).

Different designs and configurations can be used without departing from the scope of the invention.

In another embodiment, the invention is thus directed to a step for an elevating platform with a sidewall, the step includes a top flange, a bottom flange, and a transition. The top flange and the bottom flange are joined by the transition; and the step is configured to insert into a cutout in the platform sidewall. The bottom flange is configured to contact an outer surface of the platform sidewall when the top flange contacts an inner surface of the sidewall. In one embodiment, the step includes a first step notch in a first side of the transition, configured such that when the first step notch is inserted into a first cutout notch of the cutout in the platform sidewall, the top flange of the platform step is operable to be inserted into the cutout of the sidewall and the platform step is operable to be pivoted via the first step notch in the first cutout notch such that the top flange contacts the inner surface of the sidewall. Another embodiment includes a second step notch in a second side of the transition; the platform step operable to lock into the elevating platform by positioning the top flange such that the top flange contacts the inner surface of the sidewall, positioning the first step notch in the first cutout notch, and positioning the second step notch in a second cutout notch. The top flange is configured such that when the platform step is locked into the platform sidewall and adhered to the elevating platform with adhesive, the top flange of the platform step covers the cutout, thereby sealing it. The platform step is also configured such that when the platform step is locked into the platform sidewall, the top flange of the platform step compresses the inner surface of the sidewall and the bottom flange of the platform step compresses the outer surface of the sidewall, thus providing compressive bonds between the platform step and the sidewall.

In yet another embodiment, the invention is also directed to an elevating platform with a cutout to receive the top flange of the step as previously described. The elevating platform includes a first cutout notch configured such that when the first step notch is inserted into a first cutout notch of the cutout, the top flange of the platform step is operable to be inserted into the cutout of the sidewall and the platform step is operable to be pivoted via the first step notch in the cutout notch such that the top flange contacts an inner surface of the sidewall. The elevating platform and step are operable to lock together by positioning the top flange such that the top flange contacts the inner surface of the sidewall, positioning the step notch in the cutout notch, and positioning a second step notch in a second cutout notch. The top flange and the cutout are configured such that when the platform step is locked into the elevating platform and adhered to the elevating platform with adhesive, the top flange of the platform covers the cutout, thereby sealing it. The platform cutout and platform step are configured such that when the platform step is locked into the elevating platform, the top flange of the platform step compresses the inner surface of the sidewall and the bottom flange of the platform step compresses an outer surface of the sidewall, thus providing compressive bonds between the platform step and the sidewall. In one embodiment, the cutout includes a top cutout portion and a bottom cutout portion, wherein the top cutout portion is wider than the bottom cutout portion; and the platform step includes a first side notch and a second side notch. The top flange and the cutout are configured such that when the first side notch is in contact with the first sidewall at the bottom cutout portion, the top cutout portion is operable to receive the top flange. Then, the first side notch and the second side notch are operable to lock into the bottom cutout portion of the cutout, thereby locking the platform step into the elevating platform. The top flange and the cutout are configured such that when the platform step is locked into the elevating platform and adhered to the elevating platform with adhesive, the top flange of the platform step covers the cutout, thereby sealing it.

Platform Rib

Currently multiple platform sizes and shapes are manufactured via Light Resin Transfer Molding (LRTM) with molded-in ribs or via hand layup with molded-in ribs. There are several disadvantages associated with this construction. The molded-in ribs necessary to provide structural support are thick, which adds unnecessary weight to the platform. Quality issues related to molded-in ribs occur because this design is difficult to manufacture. For example, it is difficult to spray gel coat in a uniform thickness in the mold rib cavity. It is also difficult to consistently place fiberglass in the mold rib cavity. Some molded-in ribs have foam cores, and gel coat cracking can occur more easily in ribs with foam cores when compressive forces are applied such as when platform mounting studs are tightened.

Furthermore, platforms can't be stacked during shipping due to the molded-in ribs. The rib cavities in the platform mold suffer damage faster than other areas of the mold. The molded-in ribs are also required to have a slight draft so the platform can be de-molded. It is preferable if the ribs don't have a draft for mounting purposes.

A minimum of three large objects; plug, master tool, and tool are required to manufacture a platform with a single style of molded-in ribs. For example, the five different styles of 1-man platforms currently offered by Altec, Inc. require eight different plugs, master tools, and tools for a total of 24 large objects. These items take up a lot of storage space. They are also more likely to be neglected because there are so many of them to keep track of. If the 1-man platform was made with pultruded ribs according to the present invention and if it were consolidated to one platform height then it would only require 1 plug, 1 master tool, and 1 tool to produce all of the platform rib styles currently offered.

The present invention provides for a new elevating platform support system that does not use molded-in ribs, but rather uses externally-applied reinforcement ribs that address the problems described previously. The support system is inherently safer than existing external rib designs because it uses a mechanical interlock that prevents the ribs from separating from the platform if the adhesive between the platform and ribs fails. A critical feature of the mechanical interlock is that part of the rib is inside of the platform and part of the rib is outside of the platform, thus locking the rib into the platform.

The platform support system, generally described as 300 in FIG. 10, includes reinforcement ribs 310 that are fitted into slots 320 in the platform basket sidewall 215. In a preferred embodiment, the ribs are T-shaped 312 (FIGS. 11A-D). FIG. 11A shows a cross-sectional view of a T-shaped rib according to the present invention.

The example embodiment shown in FIGS. 11A-D was constructed as follows: A 8″×4″×⅜″ Series 500 I-beam manufactured by Strongwell (Bristol, Va., USA) was cut in half so two “T” shapes existed. The portion of the rib on the interior of the platform was approximately 26″ long. The rib was cut so about 4″ near the bottom of the rib would “hook” onto the outside of the platform. Two 0.75″ wide slots about 26″ long were cut in the platform sidewall and the T-shapes were bonded to the inside of the platform. The rib portion on the exterior of the platform was approximately 30″ long.

In another preferred embodiment, the ribs are an off-set double-L configuration 314, shown in cross-sectional view in FIGS. 12A-D. This latter configuration is formed by bonding two L-shaped ribs 314 (FIG. 12A, units in inches), or by pultrusion or a similar method (FIGS. 12B and C), whereby the thickness of each of the rib sections is varied to give a lighter rib with adequate strength. FIG. 12D shows a double-L rib installed in a platform. Perspective views of the ribs of FIG. 12A-D are shown in FIGS. 13A and B.

FIGS. 14A-C show another double-L design rib according to the present invention. FIGS. 14A and B show perspective views of the rib only. FIG. 14C shows the rib in a transparent platform; the rib on the right is partially installed and the rib on the left is fully installed. The exterior “L” shape preferably extends between about 1 and about 13 inches beyond the bottom of the slot to provide extra support.

In a preferred embodiment (FIGS. 15 and 16), a rib is formed from a T-shaped component 312 combined with an L-shaped component 314. T-shape and L-shape cross-sections are described as each having an arm and a stem. Herein an arm of a letter is defined as a horizontal stroke not connected on one or both ends and a stem is defined as a primary vertical stroke (see http://typedia.com/learn/only/anatomy-of-a-typeface/ for a description of typeface anatomy).

The T-shaped component 312 is inserted through a slot in the platform wall from the interior of the platform, such that it is extending outward, whereupon the stem of the L-shaped component 314 is bonded to it on the exterior of the platform.

In another embodiment (FIGS. 17A-I), the L-shaped component 314 bonded on the exterior of the platform extends below the cutout in the platform wall that accepts the T-shaped component 312 from the inside of the platform. This extension 316 allows the platform to more effectively transfer compressive stress to the L-shaped component near the outside bottom of the platform. FIGS. 17A-I show various stages of construction of the embodiment. FIG. 17A, C, E and G show views wherein the platform is solid. FIGS. 17 B, D, F, H and I show views wherein the platform is transparent.

The example embodiment shown in FIGS. 17A-I, 18A-C and 19A-C is constructed as follows:

An 8″×4″×⅜″ Series 1500 SuperStructural I-beam manufactured by Creative Pultrusions (Alum Bank, Pa., USA) is cut in half so two “T” shapes existed. Two 0.88″ wide slots are cut in the platform sidewall and the T shapes are bonded to the inside of the platform with a portion of the “T” protruding through the slots in the platform wall. The T-shaped component is 28″ long and the portion that protrudes through the platform wall is 26.25″ long. This design allows the top and bottom of the “T” to completely cover the slot cut in the platform wall to ensure a seal of the cutout. A 3″×3″×.375″ Series 1500 SuperStructural equal leg angle manufactured by Creative Pultrusions (Alum Bank, Pa., USA) is bonded to the exterior of the platform and to a portion of the T-shaped component that protrudes through the platform wall. The “L” shape is initially 36.5″ long and is cut to taper near the bottom of the platform. The “L” shape preferably extends between about 1 and about 13 inches beyond the bottom of the slot. The “L” is further trimmed so that the portion in contact with the platform is only 2″ wide instead of 3″ wide as it is manufactured. In one embodiment, the portion of the “L” that contacts the platform is trimmed even further when required, such as when the rib is close to the side of the platform and there isn't enough area to bond a 2″ wide portion. The reduced width provides adequate strength while reducing weight and the amount of adhesive required for bonding it to the platform wall. Additionally, a notch 317 is cut into the top of the stem of the T at the top of the T-shaped rib component for the following reasons:

Whenever material is removed from a component, for example by cutting a slot in it, the physical strength of that component is decreased by some amount. In an effort to minimize the strength reduction caused by the slots in the platform wall there was a desire to maintain as large of a distance as possible between the top of the slot and the platform flange.

It is desirable for the top of the “T” inside of the platform to completely cover the slot cut in the platform wall. In order to achieve this, the portion of the “T” inside of the platform must extend up past the slot cut in the platform wall. It is important that the upper portion of the “T” inside of the platform, that covers the top of the slot, doesn't extend up past the beginning of the radius where the platform wall transitions to the platform flange. This is important to minimize the interference of the portion of the rib inside of the platform with a platform liner that is inserted into the platform. Some platforms have mounting holes drilled in their ribs near the top of the rib only a few inches below the platform flange. Therefore, it is necessary for the top of the “T” rib on the outside of the platform to be no more than approximately 1.5″ from the bottom of the platform flange.

FIGS. 18A-C show the “T” shape utilized in FIG. 17. In a preferred embodiment, the thickness of the various flat parts of the “T” shape are ⅜ inch. FIGS. 19A-C show the “L” shape utilized in FIG. 17. In a preferred embodiment, the “L” shape flat parts are ⅜ inch thick.

Another example embodiment, shown in FIGS. 20A-C, is similar to the previous embodiment, with the addition that the rib portion on the exterior of the platform also extends above the interior rib portion at both ends. In other words, the stem of the “T” extends beyond the arm of the “T” at both ends of the rib. In this manner the rib “hooks” onto both the top and the bottom exterior of the platform. The dimensions of the slot and rib are adjusted so that the exterior portion of the rib fits through the slot when the longer extension end is inserted through the slot and moved to its limit.

Another example embodiment has the arm extending vertically beyond the stem of the T at both ends of the rib. One benefit of this design is that the arm completely covers the slot in the platform wall.

In another embodiment, the T stem is notched at the top of the rib so that the stem extends vertically beyond the arm while the arm still covers the slot near the top of the platform.

Yet another embodiment is for a rib that has a stem that extends above the arm at the top of the rib and the arm extends below the stem at the bottom of the rib. This design allows the arm to completely cover the slot in the platform wall while reducing the tendency of the arm to separate from the platform wall near the top of the rib during loading scenarios such as “side push” which occurs when the side of a platform is accidentally pushed into a tree.

When the stem of the T-shaped portion extends vertically beyond the arm of the T at the top of the rib, this is beneficial during scenarios when a load is being applied to the bottom of the platform (like when the platform is accidentally slammed into the ground). In this scenario, the stem of the T above the arm of the T on the inside of the platform is in compressive contact with the platform wall and this prevents the arm of the T from separating from the inside wall of the platform due to a tension force (i.e., the rib being pushed into the platform near the top of the platform).

When the stem of the T-shaped portion extends vertically beyond the arm of the T at the bottom of the rib, this is beneficial during scenarios when a vertical load is being applied to the inside of the platform (like when an operator is standing in the platform.) In this scenario, the stem of the T below the arm of the T on the inside of the platform is in compressive contact with the platform wall and this prevents the arm of the T from separating from the inside wall of the platform due to a tension force (i.e., the rib being pushed into the platform near the bottom of the platform).

In general, when the stem of the T on the outside of the platform extends above or below the arm of the T on the inside of the platform, the stem is allowed to support more force than would otherwise be supported by the arm or by the adhesive. This occurs because the stem has a greater section modulus than the arm.

FIGS. 21-26 show the assembly steps of the embodiment of FIG. 17. Slots are cut into the platform (FIG. 21), whereupon the inner ribs are inserted through the slots (FIG. 22). The inner rib is glued to the platform (FIG. 23, exterior view; FIG. 24, interior view). The outer rib is next glued in place (FIG. 25). FIG. 26 shows the compression forces acting on the rib.

In another embodiment, a lanyard anchor bracket reinforcement section 325 is attached to rib (FIGS. 27A-C and FIGS. 28A-B). In one embodiment, the lanyard anchor bracket reinforcement section 325 is constructed out of an unreinforced thermoplastic. In exemplary embodiments, the lanyard anchor bracket reinforcement section is constructed of nylon and/or urethane. However, other materials including reinforced thermoplastics and thermoset are also used for the lanyard bracket. The lanyard anchor bracket reinforcement section ensures connection between the platform mounting bracket and the lanyard anchor bracket even if the platform rib breaks between these two structures. FIG. 29 shows the embodiment of FIG. 27 further including a brace 330 to reinforce the lanyard anchor bracket. FIGS. 30A-E show various views of the brace.

FIG. 31 shows a 0.75″ thick urethane bar 335 affixed as a lanyard bracket support.

In yet another embodiment, the present invention is directed a T-and-L-shaped rib including a T-shaped portion that has a T-shaped cross-section with an arm and a stem and an L-shaped portion that has an L-shaped cross-section with an arm and a stem; the arm of the T-shaped portion is positioned inside the elevating platform and contacts an inner surface of the sidewall of the platform; the arm of the L-shaped portion is positioned outside the elevating platform and contacts an outer surface of the sidewall; the stem of the T-shaped portion extends through the sidewall slot and the stem of the L-shaped portion is external to the sidewall and extends beyond the top and bottom of the sidewall slot; and the stems of the T-shaped and L-shape portions are adhered to each other. In one embodiment, this rib further including a notch in the top of the rib in the stem of the T-shape portion at the conjunction of the stem and the arm; the notch configured such that the arm and the stem of the T-shape slide over the sidewall via the notch. Preferably, the arm of the T-shaped portion extends vertically beyond the sidewall slot at both ends when installed in the elevating platform and the the L-shaped portion extends between about 1 and about 13 inches beyond the bottom of the slot. The rib is preferably formed of fiber-reinforced thermosets, unreinforced thermosets, fiber-reinforced thermoplastics, and/or unreinforced thermoplastics.

Another rib according to the present invention is a double-L-shaped rib including a first L-shaped portion and a second L-shaped portion, both portions having an L-shaped cross-section with an arm and a stem; the arm of the first L-shaped portion contacts an outer surface of the sidewall of the platform and the arm of the second L-shaped portion contacts an inner surface of the sidewall; the arm of the second L-shaped portion extends vertically beyond the sidewall slot at both ends; the stem of the second L-shaped portion extends through the sidewall slot and the stem of the second portion is external to the sidewall; and the stems of the portions are adhered to each other or the rib is pultruded. In one embodiment, the arm of the second L-shaped portion extends vertically beyond the sidewall slot at both ends when installed in the elevating platform. The rib preferably includes a notch in the top of the rib in the stem of the second L-shaped portion at the conjunction of the stem and the arm; the notch is configured such that the second L-shape portion slides over the sidewall via the notch. In another embodiment, the stem of the second L-shape portion at the top of the rib extends above the sidewall slot. The first L-shaped portion extends between about 1 and about 13 inches beyond the bottom of the slot. The rib is preferably formed of fiber-reinforced thermosets, unreinforced thermosets, fiber-reinforced thermoplastics, and/or unreinforced thermoplastics.

Mount System

The present invention further provides for a mounting plate, system and method. Current mounting plates (FIG. 32) consist of flat fiberglass plates that have metal reinforcement encapsulated inside of the fiberglass with studs protruding from the fiberglass plate. These mounting plates are typically bonded to the exterior of platforms. When a load is applied to the mounting plate the adhesive at the top is in tension and the adhesive at the bottom is in compression. There is a greater potential for a traditional mounting plate to separate from a platform near the top of the plate where the adhesive is in tension. Other reasons why relying on adhesive as a primary joining mechanism is not preferred pertain to quality risks such as improper adhesive application, improper adhesive mixing, and improper adhesive mix ratios.

The present invention is directed to a system and method to mount components to a platform wall utilizing a joining mechanism that relies on the structural strength of the platform and the component instead of adhesive or other fasteners. The attachment method is applicable to any component that needs to be attached to a platform. An example embodiment is a valve mounting plate. The purpose of a valve mounting plate is to provide a mounting location on a platform wall for a controller assembly. The controller assembly is used by the operator to direct the movement of the platform while the operator is inside of the platform.

A common feature among the mounting systems of the present invention is that some portion of the mounting system is located inside and another portion is located outside of the platform via an opening in the platform wall. This is the design feature that allows the mounting system to be mechanically locked into a platform wall without adhesive.

Another benefit of the new mounting systems are their reduced size and weight. The reduced size also allows less adhesive to be used due to the reduced bonding surface area that is now allowed due to the redirection of stress into the platform wall and mounting plate.

Thus the present invention relies on the structural strength of the platform wall and the mounting plate to hold the two together. Adhesive is not the primary joining mechanism in this invention.

A first mounting plate example, generally described as 400, is shown in FIG. 33. This embodiment includes four studs 410 that protrude perpendicularly through the platform wall. These four studs are used to secure the controller mounting bracket to the mounting plate. The embodiment includes exterior reinforcement 415, which is wider at the bottom in order to spread out the compression load. Preferably, the bottom of the external reinforcement is between about 50% and about 100% wider than the top and the ratio of the height to the width of the wide end between about 1.4 and 2.33. Internal reinforcement 420, shown in FIG. 34, is wider at the top and the ratio of the height to the width of the wide end between about 1.4 and 2.33, also to spread out the compression load. Preferably, the top of the internal reinforcement is between about 50% and about 100% wider than the bottom. FIGS. 35A and B show cross-sectional views of the embodiment. FIG. 35B is a magnification of section A in FIG. 35A. The figures include the studs 410, the internal reinforcement 420, the external reinforcement 415, platform sidewall 215. Additionally, a spacer 430 and a dielectric cover 435 are included. The spacer is preferably silicone and the dielectric cover is preferably a non-conductive thermoplastic, such as polycarbonate.

FIGS. 36-43 show an alternative embodiment of the present mounting system. In this embodiment, one or more slots 440 are created in the platform sidewall (FIGS. 36A and B). External reinforcement 415 is attached (FIGS. 37A and B) and a mounting plate 445 is inserted through the slots (FIGS. 38A-O, with transparent platform) and rotated into position. The mounting plate 445 includes a top section 446, a bottom section 447 and a transition 448 (FIGS. 39A-0).

The bottom section 446 includes recesses 449 for stud heads (FIGS. 39C, 39E, 39G, 39I, 39J, 39M and 40A-C). In a preferred embodiment, the studs 410 are stud fasteners with large, flat heads (large-and-flat-headed stud fastener), such as stud anchor studs (FIGS. 41A-C). Preferably, the stud is formed from a bolt inserted through a large washer and welded to the washer to form the stud. Designs where the stud is formed by welding a threaded rod to a flat head, although acceptable, did not provide as much strength. The flat sides of the head help to prevent the stud from twisting. The heads are preferable perforated and non-circular so that when embedded in composite resin they do not turn when a nut or other fastener is being applied and tightened. The studs 410 are inserted through the holes in the bottom section 447 (FIGS. 42A-C) and the mounting plate is rotated into position (FIGS. 43A-F). FIGS. 43A and B show a transparent platform with the double- and single-mounting plates, respectively, in position. FIGS. 43C and D show an opaque platform with the single and double-mounting plate, respectively, in position. FIGS. 43E and F are interior views of the platform with double and single-mounting plates, respectively.

FIG. 44A-K shows a design that consists of vertically elongated rectangular reinforcement pieces with rounded corners 450 (the shape is also called stadium, discorectangle, or obrund) on the inside and outside of the platform wall. Big head studs penetrate the reinforcement pieces and platform wall and affix the reinforcement pieces to the wall. The elongated rectangular reinforcement pieces are oval in an alternative embodiment.

The reinforcement pieces 450 are bonded to the platform wall with an adhesive. The big head stud is inserted through a reinforcement piece on the inside of the platform, through the platform wall, and through a reinforcement on the outside of the platform. A non-conductive insulating cap 455 is placed over the stud heads on the inside of the platform to prevent any current from leaking through the platform wall. The insulating cap 455 is adhesively bonded in place or is connected via mechanical means. For example, the insulating cap is designed so it “snaps” into place over the stud heads when pressure is applied. The top and bottom of the reinforcement sections are rounded to reduce stress concentrations that is produced by sharp corners. The reinforcement sections on the inside of the platform extend up, past the reinforcement sections on the outside of the platform, by an inch or so. This further reduces stress concentrations by transferring more stress into the flange of the platform. All of the same materials proposed for previous designs are also used with this design.

The reinforcement sections preferably have a height-to-width ratio between about 3 and about 6. Whereas most prior art mounting plates have a height-to-width ratio between approximately 1 and 2, it was discovered that a greater height-to-width ratio was needed to prevent separation over time of the plate from the sidewall along the top and/or bottom edges.

In an example embodiment, the width of the plate 450 in FIG. 44A is about 3.5 inches wide and about 20 inches tall (area=70 square inches). The bolt head shown in FIG. 41 is 2 inches in diameter and the mounting stud is centered in the 3.5-inch-wide portion shown in FIG. 44A. Two plates with an approximately 8-inch margin above and below the top and bottom bolts do not separate when under a 175 lbs load on a 6.5-inch moment arm. Thus, the example embodiment was able to support about 95 ft-lbs with two of the plates, with a combined area of 140 square inches, without separation, giving a separation support factor of about 0.68 ft-lbs/square inch. In contrast, a prior art mounting plate that was rated to support 40 lbs with an 8″ moment arm (26.66 ft-lbs) had dimensions of about 11.5×16 inches (area=184 square inches), giving a separation support factor of 0.144 ft-lbs/square inch. By increasing the height to width ratio, the plate is able to withstand several times more load without separation along the top or bottom edges.

Yet another mounting system example embodiment is shown in FIGS. 45-48. In this system, slots 505 are created in the platform sidewall (FIG. 45). A plate 510, with at least one upper section 515 and a lower section 520 is provided (FIGS. 46A and B). The lower section has a horizontal dimension that is greater than the length of the slot, such that the platform cannot slide beyond the transition area 525. The lower section includes holes for studs 410. The plate is shown being inserted into a slot 505 in a transparent platform.

On the inside of the platform, two inner reinforcement components 530 are positioned between the upper section 515 and the platform. The reinforcement components are slotted 535 to receive the transition 525 (FIGS. 47A-D), so that the two reinforcement components contact one another when slid together and provide a reinforcement for the entire area of the upper section. FIGS. 48A and B show an exterior perspective view of the plate rotated into position in a transparent platform. FIGS. 49A and B show interior views, respectively, for a plate installed in an opaque platform. FIGS. 49C and D show exterior views, respectively, for a plate installed in an opaque platform.

Advantageously, these valve mounting systems eliminate the risk associated with using adhesives to mount the mounting plate to the platform. In particular, a tension force that is created at the top of the plate when the plate is loaded has the potential to separate the mounting plate from a platform wall. Mechanically interlocking the platform wall via a slot or cutout in the platform wall eliminates the risk of separation of the mounting plate from the platform wall. However, in some scenarios it is undesirable to cut slots or holes in the wall of the platform and/or for the platform to include interior components because a platform liner, used for dielectric insulation, may not fit in a platform that has extra mounting plate components taking up space inside of the platform. In these scenarios, it is desirable for the entirety of the mounting plate to remain on the outside of the platform.

Such a mounting system according to the present invention includes a mounting plate that wraps around the sides of the platform and around the underside of the platform flange. FIGS. 50-52 show a valve mounting plate design, generally described as 600, with side tabs 605 that wrap around the sides of the platform, a top tab 610 that wraps against the underside of the platform flange, and a main support component 615 that substantially or matingly contacts and is adhered to the planar side of the platform. The tabs are non-parallel to the main support component. They are orthogonal to the main support component or at another angle and substantially or matingly contact the sidewall of the platform and/or the top flange of the sidewall. These tabs allow tension stress, which could induce peeling at the outer edges of the mounting plate, to be transformed into shear stresses. In the preferred embodiment, the top and side edges are tabbed. In an alternative embodiment, only the top edge is tabbed. Surprisingly, this mounting system configuration supports about four times the load of prior art mounting plates when a similar moment arm is used. Studs 410 (see FIG. 41) are inserted through the plate and other components affixed to the platform with them. FIGS. 51A-D show detailed views of the embedded big-head studs. FIGS. 52A-D show this embodiment mounted on a platform. FIG. 52A is a front view; FIG. 52B is a side view, FIGS. 52C&D are top and bottom perspective views, respectively

The plate is made out of fiber-reinforced thermosets, unreinforced thermosets, fiber-reinforced thermoplastics, or unreinforced thermoplastics. The studs are adhesively or mechanically joined with the mounting plate. Alternatively, the studs are embedded in the mounting plate when it is manufactured.

FIGS. 53A-C show another embodiment that utilizes edge modifications to change the tension stress at the edges into shear stress. In this embodiment the vertical sides are tapered or stepped 620 in order to transition the load to the platform wall more gradually and reduce stress concentrations. This design is lighter than the previous design due to its smaller size and reduced bonding area. This design uses the same materials and joining techniques as previously described. FIGS. 54A-C show the embodiment of FIGS. 53A-C mounted on a platform.

The present invention is thus directed to a mounting plate for an elevating platform. The mounting plate includes an interior reinforcement piece, an exterior reinforcement piece, and at least one fastener. The interior and exterior reinforcement pieces are vertically elongated with rounded corners, and positioned on the interior and exterior of the platform sidewall, respectively. The at least one fastener is inserted through the interior reinforcement piece on the inside of the platform, through the sidewall, and through the exterior reinforcement piece on the outside of the platform. The height-to-width ratio of the reinforcement pieces is between about 3 and about 6. The fastener is a mounting stud embedded in the interior reinforcement piece. In one embodiment, the interior reinforcement piece extends above the exterior reinforcement piece. In another embodiment, the exterior reinforcement piece is wider at the bottom than the top; and the interior reinforcement piece is wider at the top than the bottom. The bottom of the exterior reinforcement piece is between about 50% and about 100% wider than the top and the top of the interior reinforcement piece is between about 50% and about 100% wider than the bottom. The plate preferably includes a spacer positioned between the exterior reinforcement piece and the sidewall and a dielectric cover positioned over the interior reinforcement piece and a head of the at least one fastener; the spacer is silicone and the dielectric cover is a non-conductive thermoplastic. The mounting plate is made from fiber-reinforced thermosets, unreinforced thermosets, fiber-reinforced thermoplastics, and/or unreinforced thermoplastics.

Another mounting plate according to the present invention includes a wide planar section, narrow planar section and a transition. The wide and narrow planar sections are in parallel planes and not coplanar and the connects the wide and narrow planar sections. The narrow planar section is inserted through a slot in the sidewall. The wide planar section has a horizontal dimension that is greater than the length of the slot, such that the plate cannot slide through the slot beyond the transition area. The wide and narrow planar sections are parallel with and juxtaposed to the sidewall, providing a top planar section and a bottom planar section. At least one of the planar sections including at least one hole and at least one fastener, preferably a mounting stud, inserted through the hole to the platform exterior. In one embodiment, the mounting plate includes two inner reinforcement components positioned between the top planar section and the platform. The reinforcement components are slotted to receive the transition, such that the two reinforcement components contact one another when in position and seal the slot. The mounting plate is made from fiber-reinforced thermosets, unreinforced thermosets, fiber-reinforced thermoplastics, and/or unreinforced thermoplastics.

The present invention is also directed to a support for mounting components to a container. The support has a front, a back, a bottom edge, at least two side edges, a main support component, a top edge with a tab, and means for attaching components to the main support component, preferably mounting studs embedded in the main support component. The main support component is substantially parallel to the main planar surface of a first wall of the container and configured to substantially contact the main planar surface of the first wall of the container. The tab on the top edge is configured to substantially contact the projection of the container, thereby transforming the tension stress along the top edge of the mounting plate into shear stress. Preferably, at least one side edge and/or the bottom edge is tapered or stepped. In one embodiment, the support includes a first side tab along a first side edge of the support; the first side tab is configured to substantially contact the exterior of a second wall of the container that is non-coplanar with the first wall, thereby transforming the tension stress to shear stress along the at least one side edge of the support. Another embodiment includes a second side tab along a second side edge of the support, wherein the second side tab is configured to substantially contact the exterior of a third wall of the container that is non-coplanar with the first and/or second walls; thereby transforming the tension stress to shear stress along the second side edge of the support. In one embodiment, the support is a mounting plate, the container is an elevating platform with sidewalls, a top flange and a bottom, and the projection is the top flange. The support is preferably made from fiber-reinforced thermosets, unreinforced thermosets, fiber-reinforced thermoplastics, and/or unreinforced thermoplastics.

In another embodiment, the present invention is directed to an anti-peel stress mounting apparatus. The mounting apparatus includes both an internal subassembly and an external plate, wherein the internal sub assembly includes two internal plates, and wherein the internal plate and the external plate are mounted on opposite sides of a platform wall.

FIG. 55 illustrates an external view of one embodiment of the anti-peel stress mounting apparatus, wherein external plates 5501 are mounted to the platform wall and wherein the four bolt ends 5503 are operable to attach to an external component. Preferably, the external plates are positioned with a top of the plate approximately 1 or more inches (2.54 or more centimeters) from a lip of the platform wall 5505. Advantageously, the anti-peel stress mounting apparatus reduces cleavage stress between the platform wall and the mounting system when secured to an external component, since the tapered or “stepped” construction of the external plate 5501 allows the stress to be redirected into shear stress normal to the plate. The stepped construction further contributes to the reduction of peel stress on the external plate 5501, since a maximum stress is applied along the stepped area, converting the peel stress into shear stress. Preferably, the stepped construction includes a series of rectangular raised thicknesses (layers) that extend away from a mounted surface (e.g., the surface of a platform wall). The layers are preferably solid, wherein the plate is constructed as a single part from uniform material. Each subsequent step of the stepped layers away from a mounted surface decreases in perimeter size, wherein dimensions of each of the rectangular perimeters of the steps are smaller in each layer further from the mounted surface. This stepped feature is similar to the tapered and stepped construction illustrated in FIGS. 53A-54C. In another embodiment, the stepped construction provides a series of raised thicknesses (layers) that have the shape of rounded rectangles, squares, ellipses, triangles, or rounded triangles, hexagons, octagons, or any other shape known in the art, including those illustrated in FIG. 66.

FIG. 56A illustrates a cutaway view of the platform with an exploded view of the internal subassembly. The internal subassembly includes two pairs of two plates, wherein each includes a first internal plate 5601 and a second internal plate 5603. The first internal plate is preferably constructed with injection molded ribs to provide structural support to the part. The second internal plate 5603 is constructed with a stepped construction similar to the external plate illustrated in FIG. 55. A bolt end is encapsulated on a rear side of the first internal plate 5601 and extends within a tubular nub (not visible) from the first internal plate 5601, through the second internal plate 5603, through bored holes in the platform wall, and to a rear face of the external plate. FIG. 56B illustrates a cutaway view of the platform with an exploded view of the anti-peel stress assembly.

In a preferred embodiment, the internal assembly is injection molded as one piece, wherein the first internal plate 5601 is overmolded onto the second internal plate 5603. The material of the first internal plate 5601 is, in one embodiment, approximately 30% glass by weight with randomly distributed, short fibers. The second internal plate 5603 is preferably constructed using fiberglass reinforced polyethylene terephthalate (PET), which includes long, continuous fibers that are oriented in an alternating 0°/90°/0° pattern, which provides high strength and stiffness characteristics. The first internal plate, the second internal plate, or the external plate are, in one embodiment, constructed from unreinforced thermosets, reinforced thermosets, unreinforced thermoplastics, and/or reinforced thermoplastics. In the overmolded embodiment, it is advantageous for fiber matrices of the first internal plate 5601 and the second internal plate 5603 to have compatible matrices so that the internal subassembly can be injection overmolded. In an alternative embodiment, the internal plates are connected by way of an adhesive or welding, including plastic welding methods such as induction welding, ultrasonic welding, resistance welding, laser welding, and friction welding.

The illustrated embodiment includes elongated second internal plates an external plates with similar dimensions to previously described embodiments (e.g., FIGS. 44A-44D). However, in one embodiment, the first internal plate is constructed with dimensions that are approximately half of the dimensions of the second internal plate but with similar length/width ratios. Further, though two bolt attachment points are provided per plate subassembly, in a further embodiment, the anti-peel stress attachment apparatus includes three or more connection points per plate subassembly. In one embodiment, the steps of the stepped shape of both the second internal plate and the external plate are oblique relative to the normal axis of the platform wall. Preferably, each step of the stepped shape is constructed closer to a midline between a first plate and a second plate. For example, in FIG. 55, as each step of the external plates are constructed further from the platform wall, a centroid of each step's shape is located closer to a vertical midline of the platform wall than the previous step.

FIG. 57A illustrates a front view of the external plates 5501. Bored holes 5701 in the external plates 5501 are preferably smaller than the holes bored in the internal plate subassembly. In one embodiment, the holes in the external plates 5501 provide a free running fit for a bolt. In an alternative embodiment, the holes are equal in size to the holes of the internal plates and/or provide a loose-running fit. FIG. 57B illustrates an internal cutaway view of the platform including a front view of the internal plate subassembly. A first internal plate 5601 includes bolt encapsulation areas 5703 that are each constructed to secure an embedded or integrated bolt, wherein the bolt extends from the first internal plate 5601 through a hole in the second internal plate 5603. The hole in the second internal plate 5603 is preferably smaller than a hole of the first internal plate 5601 but larger than a hole of the external plate.

In an alternative embodiment, the bolt is secured to an internal plate by any bonding means, such as an adhesive, and is not embedded within an internal plate. In this embodiment, an insulating cover is operable to be secured over the bolt by way welding or use of an adhesive. Alternatively, the bolt is reversibly or irreversibly attached to an internal plate, e.g., via a screw mechanism, latch mechanism, rivet mechanism, or any other mechanical or chemical attachment means known in the art.

FIGS. 58A, 58B, and 58C illustrate a front view, a perspective view, and a rear view of the first internal plate 5601, respectively. FIG. 58A further illustrates an external side of a bolt encapsulation area 5703. Support ribs 5801 on the front of the internal plate are positioned around the bolt encapsulation area 5801. The perspective view of FIG. 58B illustrates the first internal plate 5601 with a hidden view of an encapsulated bolt, which is attached to an inside of the first internal plate 5601. The bolt is encapsulated (e.g., embedded or integrated) within the first internal plate 5601 and is prevented from rotating. The bolt head consists of multiple holes, which are filled with plastic material during injection molding to secure the bolt to the rest of the body of the first internal plate 5601. FIG. 58C illustrates an inside of the bolt encapsulation area 5703, which extends from the first internal plate 5601 with a thickness equal to the second internal plate 5603 and a diameter equal to the hole 5907 of the second internal plate 5603. A nub 5901 within the bolt encapsulation area 5703 is constructed to surround part of an encapsulated bolt between the internal plate subassembly and the external plate in order to increase dielectric performance of the system and reduce the risk of electrical fault occurrence. The nub 5901 extends from an internal face of the first internal plate 5601, through a wall of the platform, and to an internal surface of the external plate. FIGS. 59A and 59B illustrate a front view and a rear view, respectively, of the second internal plate 5603. Preferably, an internal diameter of the nub 5901 is slightly smaller than a diameter of a corresponding aligned hole 6001 on the external plate 5501, wherein the aligned hole 6001 provides a free running fit for the bolt. In one embodiment, the bolt head and a non-threaded shoulder of the bolt is encapsulated in the first internal plate 5601, whereupon the rest of the screw is threaded and extends through the nub 5901. In an alternative embodiment, the nub 5901 is threaded and constructed to receive a bolt via a screw mechanism. The second internal plate 5603 preferably includes holes 5907 that are approximately 0.5 inches (12.7 millimeters) larger than a bolt head to provide dielectric protection. The nub 5901 is, in one embodiment, tubular with a circular cross section and conical in construction. In another embodiment, the cross section is any other shape operable to insulate the bolt, including a rectangle (such as a square), ellipse, or triangle, and is conical, pyramidal, cylindrical, or prismatic. In a further embodiment, the bolt contains or is fully constructed from insulating material, such as a plastic or rubber. In one embodiment, the screw is completely constructed from insulating material. In another embodiment, the screw includes a coating or covering of the insulating material. FIGS. 60A and 60B illustrate a front view and a rear view, respectively, of the external plate 5501, wherein bored holes on the external plate 5501 provide a free running fit for a chosen bolt.

In a preferred embodiment, the second internal plate 5603 and the external plate 5501 are constructed with a tapering thickness from rear face of the plate to a front face of the plate. For example, in one embodiment, the material thickness is greatest on a first step of the platform-interfacing side of the plate (5905 FIG. 59A, 6005 FIG. 60A), and each of the other steps are less thick than the first (5903 FIG. 59A, 6003 FIG. 60A). In one embodiment, the thicknesses of the steps are non-uniform. For example, in one embodiment, a first step is 0.060 inches (1.524 millimeters) thick, and a second and third step are each 0.030 inches (0.762 millimeters) thick, resulting in a 0.120 inch (3.048 millimeter) total thickness of the stepped portion of the plate. In one embodiment, a ratio of the thickness of the first layer to at least one of the subsequent layers is 2:1.

In another embodiment, the nub 5901 of the first internal plate 5601 has an internal diameter that is at least 0.5 inches (12.7 millimeters) larger than a diameter of a head of a bolt, which provides at least a 0.25 inch (6.35 millimeter) clearance distance for dielectric protection. Similarly, the nub 5901 is at least 0.5 inches (12.7 millimeters) larger than an outer diameter of a threaded portion of the bolt. A hole 5907 in the second internal plate 5603 is preferably constructed with a diameter equal to a diameter of the bolt encapsulation area 5703. The hole 6001 of the external plate is, in one embodiment, constructed with a diameter operable to accept an end of the bolt and is approximately equal to outer diameter of the threaded bolt.

FIGS. 61A, 61B, and 61C illustrate views of the first internal plate 5601, second internal plate 5603, and internal plate subassembly, respectively. FIG. 61A illustrates one embodiment of the first internal plate 5601 with encapsulated bolts 5503, which are constructed to extend through holes of the second internal plate.

FIG. 62 illustrates a rear perspective view of the first internal plate 5601 with encapsulated bolts 5503. A nub 5901 provides insulation and improves a dielectric constant of the system. FIG. 63 illustrates a front view of the internal plate subassembly, and FIG. 64 illustrates a cutaway view of the anti-peel stress mounting system attached to a wall of a platform.

FIG. 65A illustrates a partially exploded, cutaway side view of the anti-peel stress mounting apparatus, wherein the internal plate subassembly, including a first internal plate 5601 and a second internal plate 5603, are attached to a wall 6501 of the platform. An external plate 5501 is attached to an outside of the wall 6501. Each of the bolts 5503 extend from the first internal plate 5601, through a nub 5901, and through the external plate 5501. FIG. 65B illustrates a detailed cutaway side view of the anti-peel stress mounting apparatus attached to the platform wall.

In an alternative embodiment, a spacer is placed between the exterior plate and a wall of the platform, wherein the spacer is constructed from a material that provides high dielectric insulation, such as silicone.

FIG. 66 illustrates embodiments of different shapes corresponding to each of the construction of the stepped layers of internal or external plates and/or assemblies.

In one embodiment, terms such as “insulating,” “dielectric insulation,” “dielectric rating,” and similar terms relating to insulation are not intended to imply that materials are necessarily completely insulating or non-conductive. Instead, these terms convey a decreased conductivity within safe operational boundaries. For example, in one embodiment, the platform, the platform walls, the doors, the attachment mechanisms, or any other attached pieces are constructed with a dielectric rating of 70 kV. Alternatively, the dielectric rating is 50 kV. Preferably, the dielectric rating of 50 kV conforms to ANSI 92.2 Section 5.4.2.5 published in 2015, which is hereby incorporated by reference in its entirety. This standard requires the following test for a dielectric rating of 50 kV: “Platform liners used for insulation shall be tested in a conductive liquid. The liquid level around both the inner and outer surfaces of the liner shall be within 6 inches (152 mm) of the top of the liner. The liner shall withstand a minimum of 50 kV ac for 1 minute without breakdown through the material.”

Additionally, the platform and associated elements are constructed from corrosion and/or impact resistant materials. In one embodiment, the thermoset material and/or thermoplastic material is reinforced or unreinforced.

Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. All modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
